    e46 2003 325i - Auxilary Fan not working

    Hello,

    For the last few months my cabin would stop pushing air out of the fan with our without the AC on. Now, it doesn't work at all! The car does not overheat when idle, temp gauge sits right in the middle.

    About 6 months ago my car would overheat when idling. I replaced the hoses and the coolant expansion tank.

    Researching forums I understand it could be the fan is dead, the relay, temperature sensor or the fan clutch.

    Any suggestions on how to trouble shoot which one it is?

    Thank you! Love this forum, saved me a few times ;-)

    ~Michael

    Now I understand that it could be the blower motor?
